An individual that always wears Chacos. Temperature does not matter to the true Chaconian. If it's 30 degrees, or 120 degrees, a Chaconian will be in their Chacos. Elements and location does not matter to the true Chaconian. If it's raining, snowing or storming, a Chaconian will be in their Chacos. If they are at the beach, kayaking, playing Ultimate, or rock climbing, a true Chaconian will be in their Chacos. To the Chaconian, Chacos are much more than a pair of awesome sandals, it's a lifestyle.

Guy #1:"Did you see that guy wearing his Chacos yesterday? He must be crazy! It was snowing!"
Guy #2:"He's not crazy! He's a Chaconian!"
